Representatives of the Service Employees International Union (SEIU) have said the custodians went on strike to protest "violations of rights on the job, poverty wages and inadequate benefits," the article stated.

According to the article, some custodians claim to be making $7.25 an hour, a wage which is well below the average $11.25.

"I have been working as a Planned Companies cleaner for eight months and earn $7.50 an hour," said Ulises Prudencio.

"I have a difficult time paying bills and affording visits to the doctor," Prudencio added.
